Tim Ewaldsuggests that Web Services only have 4 simple operations (input, output, input/output, output/input). I think that Tim really gets it but I would have to disagree with this particular comment since I don’t see these as operations; I see them as message exchange patterns.

This is a nice post from Mark Nottingham. He talks about the lack of a good understanding of the architectural issues when we talk about Web Services. I think Mark makes a very good point. Jim and I have been thinking about this for the last couple of months

I always wanted to have a sidebar on my desktop which aggregates information and allows various actions to be just one click away. I know Linux users had sidebars for sometime but I never found one for WindowsXP I was happy with. I even started a VS.NET project to

Mark Baker linked to this post which talks about how to access O’Reilly’s Safari Bookshelf using a REST API and has some example Java code. This post made me think about the relationship between the “ProcessMessage” approach that Jim and I have been advocating and REST. Are we that

As part of my involvement in the activities of the Grid community, I’ve heard many times about yet another requirement that is “specific” to the Grid and requires special infrastructure and new toolkits: streaming. It is true that there is no WS-* specification I am aware of that

It must be me… I can’t explain it otherwise. I must have the wrong understanding.

First, it was the Grid community with OGSI and their non-standard-based, object-oriented approach to building Grid Services, then it was WS-RF with their resource-oriented view of the world and their state lifetime management, and

I just arrived in Shanghai. For part of my journey from the airport (which is impressive) to my hotel I used Shanghai’s Maglev (non-contact Magnetic Elevation and propulsion). I didn’t know there was such a thing here before I arrived and now I know that it’s supposed to be

Nemerle seems like a cool language. When we worked on the NIP runtime, Paul and I always assumed that a functional + objects programming language would be used by programmers to target it. Nemerle seems like a good candidate for demonstrating the benefits of NIP, if any :-)

I am off to Shanghai, China, to present a paper at IEEE SCC04 that Jim and I wrote few months ago. The paper is called “Assessing the Risk and Value of Adopting Emerging and Unstable Web Services Specifications” and a version of it is available as a Computing Science Technical

An email to the WS-RFmailing list makes me want to say “I told you so”. Most times, loose-coupling and scalability don’t like explicit lifetime management of resources/objects even with tricks like heartbeats and leases.
